I created this stand specifically for nail brushes and nail pointers, but it can be used for general painting too. The section called as "B" has in middle row the holes adecuated for holding the pointers.

I have uploaded different files but all of them are the same thing, the difference is that one have an English letter, another has Spanish Letter and none letter in the front side.

My first design (see pictures) had two separated trays, however the one uploaded here has a contiuos tray in the bottom.

Use M3 screws to fix each other and a M3 tap to create the threads.

The holes in the 1st step are 12mm wide, the holes in the 2nd step are 8.5mm wide and the last are 5mm wide.

In case you want to have each stand separated, I added two additional files called Cover A and Cover B which are usefull to separate both of them.
